What it delivers

The VancEpic V-RH8K-LPG 80,000 BTU Propane Tankless Water Heater is a propane tankless with a 80,000 BTU/h burner.

At a 45°F rise (mild inlet water to a 120°F set point) it holds about 2.7 GPM, 1 shower at 2 GPM; in winter, at a 70°F rise, about 1.8 GPM, less than one 2 GPM shower. Run your house through the planner.

At full fire it burns about 0.9 gallons of propane an hour. The gas line has to carry that on top of the furnace, range and dryer; a gas fitter sizes the pipe from its length and the total load.

Its exhaust runs hot, so the vent must be the material its manual lists, usually stainless; budget for the vent kit.

What size gas line does the VancEpic V-RH8K-LPG 80,000 BTU Propane Tankless Water Heater need?
At full fire it uses about 77 cubic feet of natural gas an hour or 0.9 gallons of propane. The pipe size depends on the length of the run and every other gas appliance on it; the maker's manual and a licensed gas fitter decide it.
